MACHINE POR STAINING PAPER.

TO ALL WHOM IT MAY CONCERN:

Be it known that I,"CnAnr.ns BAnTuoLoMuw, or New York, No. 595 to 601 Ninth avenue, in the county of New York, in the State of New York, 'have invented a newand improved Machine for Staining Paper; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to vthe accompanying drawing, forming part of this specification, in which drawing- Figure 1` represents a longitudinal vertical section of this invention,partly in elevation.

Figure 2 is a plan or top view ot` the same.

Figure 3 is an inverted plane ofv the color-box,

Similar letters indicate corresponding parts.

This invention relates to machines for staining or `coloring wall or other paper. The color-box or trough is made with one or more. partitions throughout its whole length, to enable me to employ different colors -in advance of each other, and so produce new combinations; andl thc discharge-openings of the several .compartments of the color-box arc made short or long, with solid parts between them, for tho purpose of producing stripes.` Other novel features will be explaineda's thc description proceeds. l

The letter A designates the frame of the machine, which is of alength equal at least to the strip of paper toAbc operated upon. The machine is provided with the usual endless apron, B, that goes around rollers C C, placed at the opposite ends of the frame. The apron is tightened by means of adjustable pieces D placed on opposite sides of the machine, and which are so arranged that their right-hand ends press against'thc journals or journal-boxes of the right-hand roller, and consequently pushthc said roller outwards, so as to tightenv the apron. Any other means can be adopted for tightening the apron. The color-box E is suspended across the forward or left-hand endof the machine, and is made in such a manner as to produce automatically different combinations, and also narrow stripes or lines of different colors. lFor the' purpose of producing combinations from separate colors, I arrange the color-box so as to deposit one color in advance of another on adjacent portions of the sheet of paper .in parallel lines. In carrying out my invention, I run a partition, F, across the whole length of the-box, soas to divide the box from its bottom upwards linto front and rear divisions or compartments. I produce numerous combinations of stripes by making some of the forward compartments overlap some of the rear compartments, as is shown in the plan view, which arrangement enables me to produce a great variety of colored lines and stripes, according to the number of compartments that are provided, the emission of colors therefrom being in alternation. I i In addition to this arrangement ot compartments, I make the openings at their bottoms, through which openings the coloring matters are discharged, of various length, instead of making the openings as long as the respective compartments. These arrangements are shown in the plan view, tig. 2, and also in the invertedvicw ofthe colophon, fig.- 3, the letter a designating openings that are on one side of the common partition, and the letter b designating those openings that are on the other side. The several openings a are arranged opposite the interspaces ofthe openings b, where the bottoms ofthe compartments are left solid, and the openings b are arrangedfopposite the intcrspaces of the openings a. In consequence of this arrangement I am able to produce a great varict)r of stripeso'r lines across the whole breadth of the paper, the margins of the several stripes blending naturally with each other,

The several compartments of the color-box are supplied with color by means of ciste'rns L arranged on a stand, K. 'The spouts of the cisterns extend to the compartmentsfthey are intended to supply, respectively,` and are governed by stop-cocks. The cisterns are provided with strainers M, through which all the coloring matters go before` they pass to the spouts, and the strain'ers, for convenience in withdrawing them to clean out the cisterns, are provided withhandles, that extend upwards through the tops of the eisterns, as shown in iig. 1. In order to prevent sediment and refuse which may be present inthe coloring materials, and also the thicker portions thereof, from escaping into the color-box, I place the spouts above the level ofthe bottoms of the cisterns, high enough to form a well or place, N, .where such sediment and thicker portions are collected and allowed to settie,'whilc only the clear and more liquid portions run off through thc spouts.

The papermarked G is secured at one ond t0 `the travelling apron by a clamp, O, that extends under the apron and over the paper, and travels with them. When the clamp-reaches the right-hand end of thc machine it comes in contact with a lever, P, that is pivoted to the frame of' the machine, or to one of the pieces D, and hrough it actuates a bell, with which it is connected by a cord, as a signal that the paper has reached the j required length, the lever P being set at the point which will give the designed limit. VThe fresh paper is taken from a rcel, H, beneath the apron, and is passed beneath and partly around a roller, I, and thence to the top of the apron and to the clamp the movement ofthe apron being accomplished by turning the left-hand roller C, and the feed of the paper being assisted by gearing that roller to the roller I in such a manner that 'they move at the same speed. The paper is not allowed to be in contact with the apron at the point where the colors are applied, but I raise the paper oil' the apron at that point by means of a supplementary table,J, whose ends are supported on the frame of the machine. The object of this device and provision is to cause thc paper to bc presented to thecolor-box in a uniform manner, and at the same level across its whole brcadth,the supplementary table being capablccf adjustment so as to be perfectly parallel with the bottom of the box, whereby the paper is made to receive the coloring matters in equal quantities and with uniformity.' Another object is to prevent injurious eiects from uneven places and roughncsses that exist in the apron, and which, when theapron and paper are in contact while the coloring matters are applied, cause inequalities and irregularities in the work, and mar it.

What I claim as new, and desire to secure by Letters Patent, is-

1. In machines for staining or coloring wall or other paper, the application and use et' thc supplementary table J, or equivalent device, between the paper and travelling apron, at the point or points where the coloring matters are applied, substantially as and for the purpose described.

2. The division of the color-box into front and rear compartments by a partition, F, so that cnc set or series of colors shall be discharged in advance of another set or series, substantially as described.

3. The arrangement ofthe several discharge-openings of thc color-box in snch a manner that those of the front compartments shall be opposite the solid intcrspaces of the rear compartments, substantially as described.

4. 'lwo or more openings in the same straight line in the bottom of a color-box, or the bottom of a compartment of a color-box, in combination with solid interspaces between such openings, for the purpose of produeing stripes of color from the same compartment or receptacle, substantially as shown.

6. The combination, with a cistern, L, for the supply of color, cfa strainer, M, constructed and arranged substantially as described.

6. The arrangement, in the supply-cistern, of n settling-well, N, substantially as set forth and described.
